Bill Cipher(human) x reader~ after Weirdmeggedon

so, weirdmeggedon is finally over! And you have come to Gravity Falls one month later to see if you can find any information about the strange Oddpacalypse that had happened. But on the way, you meet someone who may or may not be plotting something else, in revenge.
dun duNN DUUUUUUUUUNNNN
okay, so I know weirdmeggedon part 3 comes out on the 15, but I just want to make something for gravity falls so all of them diehard fans like myself, can read that's up to date! Because its so weird having to read fanfics were Dipper still doesn't know who the author of the journals are.
